Speech Nuclear energy is a mature and proven low-carbon source of electricity, with a 60-year track record of providing reliable and safe operation. Further innovation and technological development will enable even wider applications aimed at deep decarbonisation of economies around the world and supporting sustainable development. This was the message of King Lee, director of the Harmony Programme at World Nuclear Association, to delegates at the UN side event for Sustainable Development Goal 9, held today at COP25 in Madrid.
"At this side event we are discussing innovation and future technologies to drive deep decarbonisation. We have already heard at the start of this conference about the climate emergency and the widening emissions gap. This is why the world urgently needs all low-carbon energy sources to achieve its climate goals.
Nuclear is already an important part of today's clean energy.
Nuclear is the largest source of low-carbon electricity generation in advanced economies today, providing 40% of all low-carbon generation.
The IEA report Nuclear Power in a Clean Energy System, launched in May, states that, "Without nuclear investment, achieving a sustainable energy system will be much harder, and would have implications for emissions, costs and energy security."
When such an alteration is made, much energy is released in the form of heat and this is used to generate electric power. For obtaining atomic power, nuclear fission is required, which takes place in a nuclear reactor containing a heat-producing core and a cooling system.
Within the core, atoms of the fuel, usually uranium, enriched uranium or plutonium, are split. The heat released by the reactor is used to generate steam and the steam is used to generate electricity. The first nuclear power station was built in Britain in 1956 at Calder Hall.
In comparison to other traditional fossil fuels as energy sources, nuclear power produces enormous amount of energy. No other source of energy can produce such amount of power from a very small quantity of material. It has been estimated that only 1 ton of uranium produces energy equivalent to the energy produced by 5 million tons of coal.
